Tableau Semantics supports the Open Semantic Interchange (OSI), an open-source standard for sharing semantic models across various platforms and tools.
Key Benefits
- Reusability: Companies can avoid manual recreation by reusing existing semantic definitions (dimensions, measures, relationships, and business logic) from external models like Snowflake, dbt, and so on.
- Consistency: Companies can maintain a unified single source of truth across analytics tools and AI-powered experiences.

Limitations
As OSI support is based on the early v0.1 specification, some capabilities are still evolving. Considerations include:
- Calculated fields and metrics aren’t yet translated across platforms.
- Certain metadata requires manual configuration or validation, as reflected in the OSI workflow.
- Automatic synchronization between the original semantic model and Tableau Semantics is not supported.
- Full access to the Tableau semantic model is required for a successful OSI conversion.
- OSI v0.1 Overview
Tableau Semantics currently supports the initial release of the OSI open-source workflow (OSI v0.1). - OSI Workflow
The OSI workflow uses open-source translators and customer-managed infrastructure.
